Is there a recommended book for this the SharePoint courses? For the certification test?
SharePoint course Book
@Silvia-Ramirez , I hope all is well. The ONLY exam currently available that in any way touches Microsoft SharePoint is the following, which is a BETA exam for the moment:
This exam touches indirectly on SharePoint, but IS NOT a SharePoint exam, as it is security focused.
All of the other SharePoint exams have been retired over the last 18 months or so, and are no longer available.
As of now, it DOES NOT appear that Microsoft will be bringing out product specific exams on SharePoint, but rather that they will be incorporating SharePoint content into certain exams as needed to address specific topics or concepts.
If you have any other questions, please let me know.
